Finneas kisses guitarist at New York City concert

Finneas sings “1 True Love” … but it looks like he's got plenty of kisses to spare – smooching his guitarist during his show in New York.

The super producer was at Warsaw Concerts, a Brooklyn venue, on Saturday jamming for a few hours… when he and his guitarist met eye to eye and shared a sweet moment together before he leaned in and locked lips.

Check out the clip… it looks more like a playful kiss between two mates than anything romantic – but the audience still kind of goes crazy for the kiss.
